GitHub Vulnerability Alerts

CVE-2026-35029

Impact

The /config/update endpoint does not enforce admin role authorization. A user who is already authenticated into the platform can then use this endpoint to do the following:

• Modify proxy configuration and environment variables
• Register custom pass-through endpoint handlers pointing to attacker-controlled Python code, achieving remote code execution
• Read arbitrary server files by setting UI_LOGO_PATH and fetching via /get_image
• Take over other priveleged accounts by overwriting UI_USERNAME and UI_PASSWORD environment variables

Patches

Fixed in v1.83.0. The endpoint now requires proxy_admin role.

Workarounds

Restrict API key distribution. There is no configuration-level workaround.

CVE-2026-35030

Impact

When JWT authentication is enabled (enable_jwt_auth: true), the OIDC userinfo cache uses token[:20] as the cache key. JWT headers produced by the same signing algorithm generate identical first 20 characters.

This configuration option is not enabled by default. Most instances are not affected.

An unauthenticated attacker can craft a token whose first 20 characters match a legitimate user's cached token. On cache hit, the attacker inherits the legitimate user's identity and permissions. This affects deployments with JWT/OIDC authentication enabled.

Patches

Fixed in v1.83.0. The cache key now uses the full hash of the JWT token.

Workarounds

Disable OIDC userinfo caching by setting the cache TTL to 0, or disable JWT authentication entirely.
